I don't see a physical address or anything else so I would be wary.
You probably missed it, but it is written on the site
Voltage Incorporated
1050 S Sagebrush St
Wichita, KS 67230
Email Address: support @voltage.cloud
Telephone number: 620-755-1703
I checked the usual spots, the main page, the about us page and the contact us page and did not see it. So either their site is not mobile friendly or I just missed it.
However, looking at that address it is someones house not even an office in a strip mall or one of those shared office places, just a house.
Sure that the cost can easily be lowered but there are surely people who prefer to pay for a "ready to go" solution. It will certainly become a niche later on.
When you see the electricity price in some countries, it can be cheaper to run a server. If you spend $3 on electricity, well it could be better to buy a 3$ VPS with a 100 times better connection, and maybe a "better security"
what HW are they hosting on, what it the back end connection and where are they hosting
I don't know the specs of the HW, but I know that Lite and Standard nodes are hosted on shared HW, while Pro nodes are on dedicated servers.
Servers are located in The United States
Could be the way they do their marketing, but the way the pricing is shown (per hour with a per month price) looks like they are just spinning up machines on the Amazon or Google cloud (or similar) not saying that is bad but if it's a well known cloud good cloud provider that's fine. If it's DaveF hosting it's a different story.
Don't get me wrong I like seeing more things like this in the
BTC space. But without more info this service may or may not be worth it.
